Ok I've got a 95, so I know my computer is OBD II.
I've checked with some local repair shops, they want to charge a minimum just to tell me what the code is if they hook me up to their computer.

My engine light blinks for a period of time ONLY when i give it gas while going up a grade (trying to keep up to speed or accelerate up a hill).
I dont hear anything, I dont see or know of any other symptoms.

When mine did that it showed bank 1 too rich. Which could have been a number of things. It was time for a tune up so i went ahead and had that done and it hasn't done it since. Mine would flash like yours, going up hill and the engine would down shift.

01 xtreme...4.3L X-cab...Mostly stock except for the K&N filter, magnaflow convertor with single in dual out flomaster 40 series muffler. I've got 4 mtx 12's and a kicker zr360 amp. Nothing fancy, but hoping to drop in a 5.7 soon!

In my case I took it to the dealership, only because my grandma (who technically owns it) pulled rank on me and told me too. If it needs a crank relearn, not saying it does as stated above, yes you would need to take it to a shop or to someone who has a big expensive scan tool, like a Snap-On Modis or Solus or a GM scan tool. There are some others out there too. But that was just my case. Like stated before, it could be a whole boat load of other stuff.

If the have the reader to use, Have them go to the car with you and you do the reading. A flashing SES light indicates a SEVERE mis-fire. Could be a plug wire popped off the distributor, That did happen on my 96 last week.
Or just buy your own reader. Handyto have and ive seen some now as low as 40 bucks.

really? where at? Local autozone wants 60 bucks for it., and secondly will the reader tell me enough to hopefully fix the problem?

Ive been looking into it a little more, just in case I were to decide to buy a reader, BUT every reader out there seems to be for 1996 and up.
looking into that, i found a site or two that says you have to switch some pins to make the reader think you are '96, while others said you have to get "special software".

apparently Im the bastard year of '95 that is a hybred between '94 and '96, with and OBDII reader that isnt compattible with OBDII.

The auto zones in CA dont have the loan tool? I have a basic actron reader. I have always been able to figure out evry problem using it. You may have to do some research, A reader is a mechanic in a box. Not try to be smart guy but you will have to work with it.
